    摘要: A piezoresistive micromechanical sensor component includes a substrate, a seismic mass, at least one piezoresistive bar, and a measuring device. The seismic mass is suspended from the substrate such that it can be deflected. The at least one piezoresistive bar is provided between the substrate and the seismic mass and is subject to a change in resistance when the seismic mass is deflected. The at least one piezoresistive bar has a lateral and/or upper and/or lower conductor track which at least partially covers the piezoresistive bar and extends into the region of the substrate. The measuring device is electrically connected to the substrate and to the conductor track and is configured to measure the change in resistance over a circuit path which runs from the substrate through the piezoresistive bar and from the piezoresistive bar through the lateral and/or upper and/or lower conductor track.
